=pod =head1 NAME OPENSSL_VERSION_NUMBER, OpenSSL_version, OpenSSL_version_num - get OpenSSL version number =head1 SYNOPSIS #include #define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL #include unsigned long OpenSSL_version_num(); const char *OpenSSL_version(int t); =head1 DESCRIPTION OPENSSL_VERSION_NUMBER is a numeric release version identifier: MNNFFPPS: major minor fix patch status The status nibble has one of the values 0 for development, 1 to e for betas 1 to 14, and f for release. for example 0x000906000 == 0.9.6 dev 0x000906023 == 0.9.6b beta 3 0x00090605f == 0.9.6e release Versions prior to 0.9.3 have identifiers E 0x0930. Versions between 0.9.3 and 0.9.5 had a version identifier with this interpretation: MMNNFFRBB major minor fix final beta/patch for example 0x000904100 == 0.9.4 release 0x000905000 == 0.9.5 dev Version 0.9.5a had an interim interpretation that is like the current one, except the patch level got the highest bit set, to keep continuity. The number was therefore 0x0090581f. OpenSSL_version_num() returns the version number. OpenSSL_version() returns different strings depending on B: =over 4 =item OPENSSL_VERSION The text variant of the version number and the release date. For example, "OpenSSL 1.0.1a 15 Oct 2015". =item OPENSSL_CFLAGS The compiler flags set for the compilation process in the form "compiler: ..." if available or "compiler: information not available" otherwise. =item OPENSSL_BUILT_ON The date of the build process in the form "built on: ..." if available or "built on: date not available" otherwise. =item OPENSSL_PLATFORM The "Configure" target of the library build in the form "platform: ..." if available or "platform: information not available" otherwise. =item OPENSSL_DIR The "OPENSSLDIR" setting of the library build in the form "OPENSSLDIR: "..."" if available or "OPENSSLDIR: N/A" otherwise. =item OPENSSL_ENGINES_DIR The "ENGINESDIR" setting of the library build in the form "ENGINESDIR: "..."" if available or "ENGINESDIR: N/A" otherwise. =back For an unknown B, the text "not available" is returned. =head1 RETURN VALUE The version number. =head1 SEE ALSO L =head1 COPYRIGHT Copyright 2000-2016 The OpenSSL Project Authors.
